In this paper, an expert and interactive system for developing protection system for overhead and radial distribution feeders is proposed. In this system the protective devices can be allocated through heuristic and an optimized way. In the latter one, the placement problem is modeled as a mixed integer non-linear programming, which is solved by genetic algorithm (GA). Using information stored in a database as well as a knowledge base, the computational system is able to obtain excellent conditions of selectivity and coordination for improving the feeder reliability indices. Tests for assessment of the algorithm efficiency were carried out using a real-life 660-nodes feeder. © 2006 IEEE.

The need for the representation of both semantics and common sense and its organization in a lexical database or knowledge base has motivated the development of large projects, such as Wordnets, CYC and Mikrokosmos. Besides the generic bases, another approach is the construction of ontologies for specific domains. Among the advantages of such approach there is the possibility of a greater and more detailed coverage of a specific domain and its terminology. Domain ontologies are important resources in several tasks related to the language processing, especially in those related to information retrieval and extraction in textual bases. Information retrieval or even question and answer systems can benefit from the domain knowledge represented in an ontology. Besides embracing the terminology of the field, the ontology makes the relationships among the terms explicit. Copyright 2007 ACM.

The importance of science and technology (S&T) in Small Island Developing States (SIDS) is clearly articulated in Chapter XI, paragraphs 57, 58, 61 and 62 of the Mauritius Strategy for the Further Implementation of the Programme of Action for Sustainable Development of Small Island Developing States (MSI). At the regional level, the Heads of Government of the Caribbean Community (CARICOM) noted the challenge that CARICOM member States face in competing in this new international economic environment in which the impact of scientific and technological change has created a knowledge-based global economy. Given the importance of S&T to development of Caribbean SIDS, the Economic Commission for Latin America and the Caribbean (ECLAC) Subregional Headquarters for the Caribbean embarked on a study to determine the causes and consequences of low rates of specialisation in S&T with a view to making recommendations for development of strategies for addressing these challenges. Data on postgraduate (Master of Science, Master of Philosophy and Doctor of Philosophy) enrolment and graduation in agriculture, engineering and the sciences from the three campuses of the University of the West Indies (UWI) as well as from the University of Technology in Jamaica and the University of Trinidad and Tobago (UTT) were examined and analysed. Face-to-face interviews were also held with key personnel from these institutions and a questionnaire was also served to individuals in key institutions. Results of the study revealed that although the number of students enrolled in higher degree programmes has increased in absolute terms, they are decreasing in relative terms. However, enrolment in agriculture has indeed declined while enrolment rates in engineering, although increasing, were not significantly high. Market forces have proved to be a main reason for this trend while facilities for the conduct and supervision of cutting-edge research, the disconnect between science and industry and societal labelling of scientists as “misfits” are also contributing to the situation. This has resulted in a reduced desire by students at all levels of the school system and faculty to be involved in S&T; lack of innovation; a better staffed private, as compared with public, sector; and poor remuneration in science-based employment. There also appears to be a gender bias in enrolment with more males than females being enrolled in engineering while the opposite is apparent in agriculture and the sciences. Recommendations for remedying this situation range from increasing investment in S&T, creating linkages between science and industry as well as with the international community, raising awareness of the value of S&T at all levels of the education system to informing policy to stimulate the science – innovation interface so as to promote intellectual property rights.

O atual trabalho é a construção de um estudo cuja área de conhecimento se encontra nos fundamentos da história de empresas, tendo como estudo de caso a Perfumarias Phebo, uma empresa paraense, que se destacou no mercado de perfumaria nacional. O método da pesquisa consistiu no levantamento de informações arquivística referentes a implantação, trajetória histórica e evolução administrativa-financeira da Phebo, no período de 1936 a 1988, realizada a partir de informações disponibilizadas pela empresa, entrevistas e coleta de material. A empresa utilizou o pau-rosa (Aniba rosaeodora Durke), uma matéria-prima oriunda da Amazônia, para criar o seu produto de maior aceitação no mercado, o Sabonete Phebo Odor de Rosas. No contexto de desenvolvimento regional, a perfumaria internalizou o conhecimento baseada no aproveitamento das matérias-primas locais e tornou-se líder no mercado de perfumaria brasileiro com a expansão da sua fábrica para as cidades de São Paulo e Feira de Santana-Ba. Em 1988 a empresa foi vendida para o grupo Procter & Gamble Company, multinacional americana, que por sua vez, em 1998, revendeu a empresa para as Casa Granado, empresa carioca, que atualmente exerce o controle sobre a Phebo.

Este estudo objetivou realizar uma analítica do poder no documento “Declaração e Programa de Ação sobre uma Cultura de Paz”, documento este legitimado, em 1999, por uma Assembleia Geral das Nações Unidas, fixando-se assim como norte prioritário das práticas da agência intitulada Organização das Nações Unidas para a Educação, a Ciência e a Cultura (UNESCO). Foram utilizados como instrumentos de análise norteadores metodológicos vinculados a muitos operadores retirados do aporte teórico-metodológico produzido por Michel Foucault. Caminhou-se na direção de pensar, problematizar e produzir saber a partir deste movimento de desmontagem de documentos monumentos, tendo como eixo principal o conceito de “Cultura de Paz”. Este mote de cultura de paz possui sua existência atrelada à história das Nações Unidas e às suas agências, sendo produzido e sistematizado a partir de um conjunto de crenças, práticas e associações, que lhe possibilitaram ganhar visibilidade e poder, popularizando-o e tornando-o uma das produções discursivas mais significativas da contemporaneidade. Percorrendo necessariamente por diagonais entre as temáticas UNESCO, governamentalidade e produção de subjetividade, finalizamos esta dissertação com a apresentação do debate a respeito das práticas denominadas cultura de paz e seus efeitos no cotidiano em termos de saber e poder.
